Precautions
Wiring Precautions
I
Read the following before using the Amplifier Unit and Sensor to
ensure safety.
Power Supply Voltage
Do not impose any voltage exceeding the rated voltage on the
E3X-NA. Do not impose AC power (100 VAC) on models that
operate with DC. In both cases, the E3X-NA may burst or burn.
Load Short-circuits
Do not short-circuit the load connected to the E3X-NA, or the
E3X-NA may burst or burn.
Polarity
When supplying power to the E3X-NA, make sure that the polarity
of the power is correct, or the E3X-NA may burst or burn.
No-load Operation
A load must be connected to the E3X-NA during operation, or
internal elements may burst or burn. Always wire through a load.
Operating Environment
• Do not use the Amplifier Unit or Sensor in places with flammable
or explosive gas.
• Do not use the Amplifier Unit or Sensor underwater.
• Do not disassemble, repair, or modify the Amplifier Unit or
Sensor.
Power
I
Turning Power ON
The Sensor is ready to operate within 100 ms after the power
supply is turned ON. If the Sensor and load are connected to
power supplies separately, be sure to turn ON the power supply to
the Sensor first.
Turning Power OFF
Pulses may be output when the power is turned OFF. Always turn
OFF the power to the load or the load line first.
Power Supply Type
Do not connect the E3Z-NA to a full-wave or half-wave rectified
power supply.
Communications Hole
The hole on the side of the Amplifier Unit is a communications
hole for preventing mutual interference when Amplifier Units are
mounted side-by-side. The E3X-MC11 Mobile Console (sold
separately) cannot be used.
If an excessive amount of light is received via the Sensor, the
mutual interference prevention function may not work. In this
case, make the appropriate adjustments using the sensitivity
adjuster.
The mutual interference prevention function will not operate when
the E3X-NA is used side-by-side with E3X-DA-N models.

Wiring the Amplifier Unit
I
Cable
The cable can be extended, provided that the extension wire
2
applied is at least 0.3 mm
thick and the total distance no more
than 100 m.
Do not pull the cable with a force exceeding 30N.
Separation from Power or High-tension Lines
Do not wire power lines or high-tension lines alongside the lines
of the Amplifier Unit in the same conduit, otherwise the Amplifier
Unit may be damaged or malfunction due to induction. Be sure to
wire the lines of the Amplifier Unit as far as possible from power
lines or high-tension lines or laid in an exclusive, shielded conduit.
Power line
Power Supply
If a standard switching regulator is used as a power supply, the
frame ground (FG) terminal and the ground (G) terminal must be
grounded, or faulty operation may result from the switching noise
of the power supply.
M8 Metal Connectors (Water-Resistant Models)
Turn OFF the power before inserting or removing the connector.
Hold the connector cover when inserting or removing the
connector.
Tighten the fixing screws by hand. Using tools such as pliers may
cause damage.
The applicable tightening torque range is 0.3 to 0.4 N·m. If tight-
ening is insufficient, the enclosure rating may not be maintained,
and vibrations may cause the connector to come loose.
